EDWARD POSSON, OF CHTCAGO, ILLINOIS.

HATCH-COVER ANDV VENTILA TOR FOR REFRIGERATOR-CARS.

Specification of Letters Patent.

Patented Sept. 2, 1,913.

Application filed February 29, 1912. Serial No. 680,729.

To all whom t me concern:

Be it known tiat I, EnwAnnPossoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented cert-ain new and useful Improvements in Hatch-Covers and Ventilators for Refrigerator-Cars, of which the following is a specification.

The principal' object of my invention is to provide a new and improved cover for the hatchway of a refrigerator car.

Another object of my invention is to provide such a cover with means for Ventilating the car.

Another object of my invention is to rovide a hood over the hatchway of a re rigerator car with a plug for opening or closing the hatchway and improved means for Ventilating when the plug is opened.

All these objects and others will be made clear in connection with the following speci ication and claims, taken with the accompanying drawings. In these drawings I have illustrated one specific embodiment of my invention and a modiication thereof. I now proceed to describe these particular forms of the invention.

Figure 1 is a perspective view of the hood in closed position. Fig. 2 is a longitudinal vertical section. Fig. 3 is a top plan view partly broken away, and partly in section on the line 3-3 of Fig. 2. Fig. 4 is a horizontal fragmental section on the line 4-4 of F ig. 2. Fig. 5 is longitudinal vertical section of a modification.

- Referring first to Figs. 1 2, 3 and 4 the refrigerator car roof 15 has the usual hatchway 16 at the end over the ice box. This hatchway 16 has downwardly converging side walls 17 and may be closed by the plug 18 which has packing 19 around its sides. @ver the hatchway 16 is a .hood designated generally by thereference numeral 20. The frame composed of the angle irons 39 and 40 surrounds the upper edge 38 of the hatch way 16. At one side this frame carries the stationary members of the hinge 21, the movable members 45 being riveted to the outside of the sloping face 22 of the cover 20. Short alining shafts 24 are journaled in two opposite side walls of the hood 20. Within the hood these shafts 24 are rigidly connected to the ends of the arms 25 of the bail 26. The plug 18 has` two iron straps 27 bolted thereto, but spaced from the plug so as to form slots 28 through which the bail 26 passes. Outside of the casing 20 the lever or crank arm 29 is connected to one of the short shafts 24, and by this means the bail 26 may be rotated. At the side of the 4hood 20, away from the hinges 21, the top cover is bent upwardly, as designated by the reference numeral 30, and carries the handle 46. The side of the hood 20, away from the hinges 21, is composed of a sheet metal plate 31 below and woven wire netting 32 above. Inside of the hood 20 back of the netting 32 is a depending baille 33. Below this baffle 33 the hood carries two defieetors 34 and 35 which catch any water that may run down from the baille 33 or down the inside face of the wall 31, and direct such water upon the roof of the car. The hood 2O carries a staple 37 which may be engaged by a hasp 36 on the roof in order to fasten the hood down. The plug 18 carries eyes 42 which are loosely engaged by the studs 43 on the ends of the arms 41. At their other ends these arms are connected by hinged points 23 to the hood 22. The spaced loops 47 on the plug 18 over the arms 41 permit only slight angular movements of the plug 18 relatively to said arms 41. The hinge members 44 lie directly under the, outside hin e members 45 and are riveted together wit the sloping wall 22 of the hood between them. As shown in Fig. 2 the opening in the eye or lug 42 is slightly elongated, so that the stud 43 and said eye 42 can be relatively slightly displaced. As shown in Fig. 2, the plug 18 is closed. lVithout raising the hood 20 the plug 18 can be opened by throwing the lever 29 over about 180 degrees. The slots 28 under the straps 27 permit the bail 26 to `slide therein. The dotted lines in Fig 2 show the relation of the parts when the plug 18 is opened up. It will be seen that the bail 26 has a wedging action to close the plug; that is, in the full line post tions of the parts in Fig. 2 a downward pressure on the lever 29 gives a powerful mechanical advantage to crowd the plug 18 down into the hatchway 16. On the other hand, when the plug is to be raised the arrangement of the parts gives a powerful mechanical advantage for this pur )ose to an upward pull on the lever 29. The plug 18, being carried on the ends of the arms 4l, can move relatively thereto and so take an angular position accurately fitting into the hatchway. Also, the plug 18 can be displaced a little horizontally in any direction by virtue of the pin and slot connections 42, 43. rlhe wire netting 32 is of fine enough mesh so thatit arrests most of the water in the air going through it. rllhe water arrested on the netting, 32 will run downlthe same and down the wall 31 partly on the inside and partly on the outside thereof. Any water that may chancev to be carried under the hood 20 by air passing through the netting 32 will be caught on the baiiie 33 and drip down from the lower edge `thereof to the deflector 34.

Referring now to the modified embodiment of myl invention shown in Fig. 5, the 'plug and the mechanism for operating 1t are substantially the same as already described. rlihe hood2() is made so as to take the air in a reverse direction as compared with the hood shown in Figs. 1 to 4. The sloping upper wall 22 of the hood 20 is continued as 22 and then bent down to form a baffle 33. Between the portions 22 and 22 is placed the vertical perforated screen of wire mesh designated 32. From the upper edge of this screen 32 the curved sheet metal wall 30pextends and connects with the upper edge of the side wall 31. The handle 46 is attached to the top part of the hood 20. ln this formV of my invention the operation of the plug is the same as previously described. It will be .seen that the hood is adapted to take in air 1n the reverse direction as compared with Figs. 1 to 4. The baffle 3.3 delivers its water on the deector 34. The curving wall 20 and the baffle 33 bound a conduit through which the air passes from the screen 32 under the lower edge of the baffle 33 and thence down into the hatchway 16.

lt will be seen that l have provided a convenient Ventilating closure for a refrigerator car hatchway, that is simple and inexpensive to construct, easily operated by persons of ordinary skill, and not liable to get out of order.
